sectok provides initialization, input, output, and other basic routines
for ISO 7816 smart cards. Many of the routines return a status word. This
will either be an error code as given in the include file, or an SW1/SW2
pair as specified in ISO 7816.
sectok_open() opens a connection to a smart card via serial port number
rn. Ports are numbered from 0, which corresponds to /dev/tty00 on UNIX.
If there is no card in the reader, sectok_open() will either wait for
card insertion, or if flag STONOWAIT is given, it will return immediately
with error STENOCARD. swp points to a status word that will be set on re-
turn.
sectok_friendly_open() opens a connection to a smart card via a reader
device name rn. Mapping from reader name to serial port number is the
same as used in sectok_open(). For other arguments and return values, see
sectok_open().
sectok_reset() resets the card and returns the ATR in the buffer pointed
to by atr if it is not NULL. If the STRFORCE flag is given, a connection
to the card will be established using default protocol parameters even if
the card ATR is illegal.
sectok_apdu() sends an APDU to the card with optional IN and OUT data.
cla application class
ins instruction code
p1, p2 per ISO 7816-3 or application dependent
ilen length of IN data
ibuf pointer to IN data
olen length of OUT data
obuf pointer to OUT data
swp pointer to return status word
sectok_cardpresent() returns whether a card is present in the reader.
sectok_close() closes a connection to a smart card.
sectok_selectfile() selects a file given its FID by sending a "select"
apdu to the card.
sectok_fmt_fid() returns a printable name for a FID.
sectok_parse_atr() parses a card ATR and returns the protocol parameters.
If the STRV flag is given it will print the parameters to standard out.
sectok_parse_fname() translates a printable name to a FID.
sectok_print_sw() looks up the error message string affiliated with a
status word and writes it to standard out.
sectok_swOK() returns 1 if sw indicates success, or 0 if it indicates
failure.
